Vintage Clothing..a good find?

I have found a box that contains a Baby Book that belonged to a boy born August 25, 1915. Also in the box are articles of clothing including a christening gown, little soldier type outfit and hand knitted sweater with little notes pinned on identifing the items as the possesions of the baby in the book. Also included: a baby blanket, booties, socks, brush and powder set, hat, pillow case and wooden ball and cup toy. There are also very old pictures of a child one would assume to be this boy. Is this stuff at all marketable as a set?
